City mistakenly posted a video interview with the 23-year-old at the end of July, in which he confirmed his medical at Bridgewater hospital, before removing the content from their official website.

But with Mangala now back from his post-World Cup holiday, the club are hopeful they can finally make the signature official and complete their final major piece of transfer business this summer.

Earlier in the window Bacary Sagna arrived on a free transfer from Arsenal, goalkeeper Willy Caballero was brought in from Malaga and Porto midfielder Fernando signed for £12m.

Manuel Pellegrini's side had tried to sign both Mangala and Fernando in the January transfer window but Porto stood firm, and in the case of the central defender even blocked his rights holders from sanctioning a deal below the club's asking price.

City's summer spending has been restricted by Uefa's Financial Fair Play penalties, with the club able to avoid a £49m fine if their outlay is restricted to the same amount and wages remain at the same level as the 2013-14 season.
